Data breaches are on the rise for all kinds of businesses, including retailers.

At least 20 consumer companies reported data breaches since January 2018. Many of them were caused by flaws in payment systems either online or in stores.

A report published by cybersecurity firm Shape Security showed that 80-90 of the people who log in to a retailer's e-commerce site are hackers using stolen data. This is the highest percentage of any sector examined in the report.

These data breaches are a real danger for both companies and customers, as they can damage the trust shoppers have in brands.

According to a study by KPMG, 19 of consumers said they would completely stop shopping at a retailer after a breach, and 33 said they would take a break from shopping there for an extended period.

But one expert from a personal virtual network service provider said that he's worried about the ultimate fallout from all these breaches.

"Due to frequent cyber-attacks and data leaks, people are becoming less attuned to privacy risks," Daniel Markuson, a digital privacy expert from NordVPN, said in a statement. "This may lead to a careless attitude towards their own personal safety, and that would mean more severe damage for all internet users."

Macy's confirmed Tuesday that some of its online shoppers' payment details were compromised after hackers cracked into its "Checkout" and "My Wallet" pages.

The department store chain alerted customers about the issue in a letter sent out on Thursday.

"We are aware of a data security incident involving a small number of our customers on Macys.com," a representative from Macy's said in a statement to Business Insider on Tuesday. "We have investigated the matter thoroughly, addressed the cause and have implemented additional security measures as a precaution."

On August 14, grocery chain Hy-Vee announced that it has launched an investigation to look into unauthorized transactions made at some of its fuel pumps, drive-thru coffee shops, and restaurants.

In a statement online, the company said that it didn't believe that other payments made in its grocery stores, drugstores, or convenience stores had been impacted.

On August 1, Poshmark released a statement on its website saying that "data from some Poshmark users was acquired by an unauthorized third party." The company said that the stolen data "does not include any financial or physical address information" and that it shouldn't have compromised any passwords.

The online clothing marketplace was hacked despite using "one of the stronger algorithms" to "scramble passwords," TechCrunch reported.
